Want real time graph in VB6

[acjeff]

Hi folks,

I use VB6 to drive an automation machine and take force data and distance vs time.

Now, I need a real time graph showing the data curve while running a test. The problem is I need to take every data in a real short time period, says, 0.1ms period (actually it takes 2000 data points in 200ms).

Here is my question: I tried a third party graph (Gigasoft ProEssentials v.3.0) but obviously its response time is not fast enough. Their technical support told me about 100 ms per update.

So, what is the best way I can do real time graph? Any other third party or plug-in software I can use? Or, do I need to use the other program like Java or C++ instead of VB?

I don't know of any graphing components that will respond fast enough for your requirements.

probably C++...

that is ALWAYS your best bet when It comes to highspeed graphics (unless you are really good at Assembly language ;-))

On the otherhand...

Can you store the point data every .1ms and update the graph on a timer?, say every 2-5 miliseconds... you probably would not visually notice a difference...
